Temperature controller for standard rail mounting, -10…+40…°C

ITR 79.408

Temperature controller for standard rail mounting, -10…+40…°C

Electronic temperature controller for controlling and monitoring of temperatures in halls, greenhouses and underfloor heating systems. The device has a sensor failure and sensor short circuit fuse and a “heating” display. The sensor is not included in the delivery. All sensors with the number 3 can be used, e.g. KF-3. The hysteresis can be adjusted between approx. 0.5…5K.
